Specifications

1. stored in a cylinder
2. a kind of compressed liquefied gas
3. non-destructive to ozone layer in the atmosphere

Hexafluoropropane(HFC236fa)extinguishant stored in a cylinder is a kind of compressed liquefied gas, which is colorless, non-corrosive, non-conductive and non-destructive to ozone layer in the atmosphere. Hexafluoropropane (HFC236fa) extinguishant is an ideal substitute of Halon 1211, suitable to fill a protection, also suitable to the site having man of all flooding.

Q:Is the heterocyclic compound not a derivative of cyclic hydrocarbons? why?
Aromatic hydrocarbons referred to as "aromatic", usually refers to the molecules containing benzene ring structure of hydrocarbons. Is a kind of closed-chain class.
Q:What is the hydrocarbon thing
Hydrocarbons can be divided into: open chain hydrocarbons (carbon atoms in hydrocarbon molecules in open chain) - saturated hydrocarbons - alkanes - unsaturated hydrocarbons - olefins and polyolefins (carbon - carbon double bonds, unstable) - alkynes and (Cyclopentane) - cycloalkene - cycloalkyne aromatic hydrocarbon - monocyclic aromatic hydrocarbon (benzene and its homologues) - fused ring aromatic hydrocarbons (Polycyclic aromatic hydrocarbons and their homologues) - polycyclic aromatic hydrocarbons (naphthalene, anthracene and other condensed ring aromatic hydrocarbons and their homologues) all hydrocarbons are hydrophobic, that all the hydrocarbons are not soluble in water and coal The main ingredients are hydrocarbons
Q:Organic organic compounds are organic matter?
Organic matter is defined as the presence of hydrocarbons and their derivatives, and the presence of covalent bonds is a feature of them.
Q:Why is the chemical name in the uncommon word so much?
The title as a Chinese people are not proud of it Do not let you change the way back? Japanese back a element you a cycle almost finished finished ok Chinese can also sideways back to the back of foreign chemistry can cycle table How much is the back? Chinese people want to back half a day to solve the ok
Q:What is the difference between crude oil and asphalt?
Difference: Asphalt is composed of different molecular weight hydrocarbons and non-metallic derivatives of dark brown complex mixture, is a high viscosity organic liquid, was liquid, the surface was black, soluble in carbon disulfide. Asphalt is a waterproof moisture and corrosion of organic cementitious materials. Asphalt can be divided into coal tar pitch, petroleum asphalt and natural asphalt three: Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural asphalt is stored in the ground, and some of the formation of ore or in the crustal surface accumulation. Asphalt is mainly used for coatings, plastics, rubber and other industries and pavement and so on. Crude oil (44.27,0.27,0.61%) is the upstream raw material of asphalt, there is a strong correlation between the two prices. For the asphalt industry, the impact of the upstream industry is mainly reflected in the fluctuations in crude oil prices, crude oil processing capacity changes in oil asphalt production and product prices fluctuations. From the downstream demand point of view, asphalt products are mainly used in highways, municipal roads, bridges and airports and other places of the laying of which highway construction for the consumption of asphalt accounted for 82%. In the case of a certain capacity, the increase in downstream demand will further promote the growth of asphalt prices, on the contrary, will bring the price down.
Q:Inorganic chemistry employment direction? Current research direction
Inorganic chemistry is the science of the composition, nature, structure and reaction of inorganic matter, which is the oldest branch of chemistry. Inorganic substances include all chemical elements and their compounds, except for most of the carbon compounds. (In addition to carbon dioxide, carbon monoxide, carbon disulfide, carbonates and other simple carbon compounds are still inorganic substances, the rest are organic matter.) Inorganic chemistry is in addition to hydrocarbons and their derivatives, the nature of all elements and their compounds And their reaction to experimental research and theoretical interpretation of science, is the development of the discipline of the earliest branch of a discipline.
Q:What is carbohydrate? What is organic? What is it?
Carbohydrates, also known as carbohydrates, are the most abundant and most widely distributed organic compounds in nature. Mainly by the carbon, hydrogen, oxygen composition. Glucose, sucrose, starch and cellulose all belong to carbohydrates.
Q:High school chemical hydrocarbons with hydrocarbon derivatives with water solubility
Hydrocarbons are insoluble in water and have a lower density than water
Q:What are the inorganic compounds
The inorganic compound is a compound other than an organic compound. Organic compounds are organic matter containing C (carbon), in addition to CO2, carbonated, carbonate-containing.
Q:Is polyethylene a derivative of hydrocarbons?
The definition is yes
